My Little Sister Is Being A S*ut! What Do I Do?
Okay excuse my choice of words for my title but I am extremely angry at my little sister right now. She is doing things that I never thought she would ever do. I will fill you in on everything.
My sister is 16 and just got out of an abusive relationship with her 19 year old boyfriend (we willl call him Ben). Everyone is so happy that she got away from him, but it seems as if things are worse than before. I have been happily dating my boyfriend for 2 years we are both 18 and we are the perfect match imaginable. We are planning to get married in the next few years. She recently had been hanging out with my boyfriend's older brother who is 21. My mom being the idiot she is, didn't care as long as she was away from Ben. I walked in one day on my sister and my boyfriend's brother having sex and I almost died. Everyone said that it was none of my business and it would never get that far, but it did and I told everyone it would. I don't know if you can imagine it, but I was very good friends with my boyfriend's brother and he and my sister both told me they would never have any kind of relationship they only liked talking. I was lied to and betrayed to by both of them and I cursed them both out pretty badly, I was in tears and so upset. Me and my boyfriend are now scarred for life from what happened, I don't think we can ever forgive them for what they did. They are remorseless for having sex, and claim that it is none of our business and it doesn't affect us. And while she was doing this with my boyfriend's brother, a guy I know and talk to sometimes (who is 20) just told me he and my sister have had sex over 20 TIMES IN TWO WEEKS. I couldn't believe it, and what's worse, she is not dating her boyfriend anymore, but is giving him oral sex and sex for money. So all of these guys at once she is having sex with.
I can't do anything but complain to my mom about it and tell her that my sister is hurting herself by having so much sex with older men. But she ends up getting mad at me telling me "Well you have sex with your boyfriend, mind your own business, its her decision what she does." I don't know what to do, my family just attacks me for getting mad at my sister, and they make excuses for her because she just got out of an abusive relationship. My family is against me, not her. I don't know what to do, but I am moving out soon and getting away from this. My sister is ruining her life AND mine because of what she did with my boyfriend's brother. HELP?
